BUILDING CONSTRUCTION Cecil Schaaf, Flint, Mich.

Application September 23, 1946, Serial No. 698,690

(01. .me-a 4a 3. Claims.-

This invention relates to building construction and more particularly to a construction in which piers or supportingcolumns are provided for carrying the roof load, which piers or columns are braced by means of horizontally disposed bracemembers to which, the, metal lath and interior finish of the building can be easily and rigidly secured.

One ofthe prime objects of the invention is to design a pre-f-abricated wallunit and bracing means including anailing; groove formed integral therewith for receiving and guiding the nails, and alsoforclinching the end sections of said nails'as they-aredriven to position.

Another object is toprovide a plurality of relatively small crimps or channels in the face of the strips for guiding the nail body and preventing sidewise deflection as it is being driven.

A further object is to provide simple, practical, and substantial means slidably engageable with the inner wall of a building for spacing the inner and outer walls from each other.

A still further object is to provide a very simple, practical and inexpensive construction in which the nails are automatically clinched as they are driven.

A further object still is to design a building wall construction that will be firm and substantial when erected; that can be easil and quickly set up, and that can be constructed at a minimum cost.

Still a further object is to provide readily removable means for supporting the wall sections in upright position as the wall is erected.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion, and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawings:

Fig. 1 is a. fragmentary, perspective View of the wall of a building with my new construction incorporated therein.

Fig. 2 is an enlarged, transverse-sectional view.

Fig. 3 is an enlarged, fragmentary, perspective view of the wall showing a modified construction in which steel members are used.

Fig. 4 is an enlarged, sectional, end-elevational view showing a nail securing a piece of wall board in position thereon.

Fig. 5- is afragmentary, perspective view of the-column form. 7

Referring now more particularly to the drawings inwhich I- have shown the preferred embodiment of myinvention. The Wall of the build1- ing is preferably made up of prefabricatedsections W, theends of which are anchored in spaced-apart piers 8 and 9 respectively, and these sections can be of a-ny'required size to suitthe building to be constructed.

Basically, the wall seetionsare identical, each section comprising a plurality of studs I fl'suitabl y spaced to suit the wall requirements, the'lo'wer ends of the studs being secured to-a foot plate I I which is securedon footings t2; and a header plate I3 is provided on theupper ends of. the studs as usual.

Horizontally disposed members B span the inner edges of the studs I0 and are formed as clearly shown in Figs. 3 and 4 of the drawings, the edges of the studs being cut as shown at I4 to accommodate the cylindrical section I5 of the members B, the lip I6 lying in facial contact with the one edge of the stud when assembled, so that no nails or other securing means are necessary to secure the members in position.

These members B are disposed in horizontally disposed, vertically spaced relation, and are preferably rolled from a relatively thin strip of metal, the sheet being circumferentially grooved as at I! and for a purpose to be presently described.

The point of bend or break I8 between the fiat lip I6 and the rolled section I5 of the member B forms an entrance to the nail grooves I'I so that nails N may be readily driven for securing plaster board P, metal lath, or other interior finish (not shown) to the members B, the nails following the circumferential grooves ll so that there will be no side deflection, and the nails are automatically clinched as they are driven.

The piers 9 and I!) can be either pre-cast or poured when the wall is being erected, forms F being provided for pouring on the job, the one edge of each side member I9 of the form being cut away as at 20, similar to the studs I0, so that it accommodates the end sections of the members B, and the front and back face 2| and 22 respectively of the form are flat as shown, and it will be clearly obvious that when the wall sections are placed in position with the ends of the members B extending into the forms, that these ends will be cast solid in the piers, thus providing a rigid. substantial construction.

It will, of course, be obvious that where the piers are pre-cast, that the cast sections will be corded to accommodate the ends of the members B, thus eliminating the forms above-described.

An outer Wall W spans the piers 9 and i0 and can be formed of concrete panels 23, brick, or any other suitable material, tie-clips 24 serving to tie the inner and outer walls together, the one end of the clip being turned as at 25 to form a clasp to engage the lip it of the member B, the opposite end being corrugated as at 26 and is disposed in the joints in the outer wall, this clip and connection being sufficiently resilient to permit limited movement of the inner and outer walls with relation to each other without cracking etc.

In Fig. 3 of the drawing I have shown a slightly modified construction in which metal studs 21 are substituted for the Wood studs l0, brackets 28 being welded or otherwise secured thereto, the bracket legs 29 being cut away as shown to accommodate the rolled section i5 of the members B, otherwise, the construction is the same. These wall sections are very simple and easy to erect, the finish can be readily applied, window and door openings can be provided as desired, and the entire building can be erected in a very short period of time and without skilled labor.

The construction is simple, practical and economical; it meets all modern building requirements and has many advantages over the conmetal member coiled to iorm an overlap of predetermined length over the inner end section of said member with the outer free end section of said member bent laterally and terminating in a flat projecting lip, and circumferential corrugations in the overlapping rolled sections of the sheet to accommodate nails therein, the corrugations in the overlapping sections forming open passages of predetermined curvature leading from the point of lateral bend of the outer end section to clinch the nails as they are driven into said passages.

2. The combination defined in claim 1 in which the outer face of the fiat, laterally projecting lip section is substantially fl-ush with the outer wall of the coiled sheet.

3. The combination defined in claim 1 in which the corrugations are closely spaced and the point of bend of the outer free end of the strip forms an entrance and guide to said passages.
